And electromagnetic type reversal valve 3 selects three position four-way directional control valve, manual type reversal valve 4 to select two-position four way change valve, electricity
The A hydraulic fluid port of magnetic-type reversal valve 3 and the K hydraulic fluid port of manual type reversal valve 4 all rod chambers with the oil cylinder 51 of two safety tongs 5 are connected,
The B hydraulic fluid port of electromagnetic type reversal valve 3 and the L hydraulic fluid port of manual type reversal valve 4 are all with the rodless cavity of the oil cylinder 51 of two safety tongs 5 even
Connect, the P hydraulic fluid port of electromagnetic type reversal valve 3 and the M hydraulic fluid port of manual type reversal valve 4 respectively with two vibrations hydraulic mechanisms 13 force feed valves
The oil-out of 137 connects, and the P hydraulic fluid port of electromagnetic type reversal valve 3 and the M hydraulic fluid port of manual type reversal valve 4 shake hydraulic pressure with two respectively
The oil-out of the force feed valve 137 of mechanism 13 connects, it addition, the P hydraulic fluid port of electromagnetic type reversal valve 3 and the M hydraulic fluid port of manual type reversal valve 4
The most all being connected with accumulator 2, the P hydraulic fluid port of electromagnetic type reversal valve 3 and the M hydraulic fluid port of manual type reversal valve 4 the most all pass through oil with fuel tank 7
Pipe connects, and the oil-out shaking the force feed valve 137 of hydraulic power source 1 is also connected by oil pipe with accumulator 2, entering of oil sucting valve 136
Hydraulic fluid port is connected by oil pipe with fuel tank 7, and in order to increase safety, accumulator 2 is connected with fuel tank 7 also by overflow valve 8.
On the other hand, the travel switch of pneumatic limiter of speed 6 644 is electrically connected with the commutation control of solenoid directional control valve 3, i.e. when
When travel switch 644 transmits a signal to solenoid directional control valve 3, solenoid directional control valve 3 can commutate accordingly.
When the present invention uses, upper plate 11 can be arranged on car frame by bolt, and the driving wheel energy of elevator and BOGEY WHEEL
15 are connected by steel wire rope, and now upper plate 11 is fixed, and lower plate 12 can make certain motion, and the oil cylinder 51 of safety tongs 5 is arranged on
On car frame, two safety blocks 53 are separately mounted to the both sides of car, and are on cage guide, changing of hand-operated direction valve 4
Being arranged in car to handle, hand-operated direction valve 4 relies on spring force to be in left position, is passed through by the installing plate 65 of pneumatic limiter of speed 6
Bolt is arranged on car, and other Hydraulic Elements may be mounted in Hydraulic Station, and solenoid directional control valve 3 is in middle position, now,
Safety tongs 5 does not works.
When elevator works, BOGEY WHEEL 15 is drawn by driving wheel, and car moves up and down, owing to car is when mobile
Can carry out certain vibrations so that BOGEY WHEEL 15 also can carry out certain vibrations, the power of BOGEY WHEEL 15 vibrations is acted on by axle 14
In lower plate 12, lower plate 12 also makees certain vibrations, and the first spring 131 can hold lower plate 12 when lower plate 12 shakes, so
Lower plate 12 can move up and down in certain scope, then also can be in certain scope with the fixing pull bar 132 of lower plate 12
Move up and down, and owing to plunger 134 contacts with pull bar 132, and plunger 134 is limited by the second spring 133, so post
Plug 134 also can move up and down in certain scope with pull bar 132.
When plunger 134 moves downward, the space in valve body 135 increases, and the inside pressure reduces, the spool of oil sucting valve 136
Opened by atmospheric pressure, oil sucting valve 136 draw oil being stored in valve body 136 from fuel tank 7, and when plunger 134 is upwards transported
Time dynamic, the space in valve body 135 reduces, and the inside pressure increases, and the spool of force feed valve 137 is opened by atmospheric pressure, and force feed valve 137 will
Hydraulic oil in valve body 135 is forced in accumulator 2, and owing to BOGEY WHEEL 15 is in car moving process, can constantly shake,
Therefore plunger 134 also can constantly move up and down and be stored by hydraulic oil in accumulator 2, i.e. stores energy to accumulator 2
In, and when the hydraulic oil stored by accumulator 2 is too much, then overflow valve 8 can be opened so that a part of hydraulic oil of accumulator 2
Return in fuel tank 7.
Meanwhile, when car up/down moves, car can drive pneumatic limiter of speed 6 up/down together to move, and up/down is moved through
The air-flow produced in journey can by airduct 62 upper below the hole 631 of ventilating board 63 enter in airduct 62, and through balloon
After 61, from airduct 62 lower above the hole 631 of ventilating board 63 flow out, and up/down side enters airflow function on balloon 61,
Balloon 61 can be promoted to carry out lower/upper movement, up/down moves again balloon 61 can by connect rope 67 pull be positioned at lower above
The sliding seat 642 of switch 64 moves, and makes to be compressed the spring 643 of inductive switch 64.
When car is in normal speed, owing to the size of air-flow is limited, the movement of balloon 61 is limited, the pressure of spring 643
Contracting is within the specific limits so that sliding seat 642 displacement is the most limited, and sliding seat 642 will not touch travel switch 644, i.e.
Solenoid directional control valve 3-dimensional is held in room, and safety tongs 5 does not works, and car normally moves.
And when the speed of car overruns, air-flow can increase accordingly, the mobile range of balloon 61 increases, switch
The spring 643 of 64 is further compressed, and the displacement of sliding seat 642 increases and touches travel switch 644, then travel switch
644 transmit a signal at solenoid directional control valve 3, and left position changed to by solenoid directional control valve 3.Now, the rod chamber of the oil cylinder 51 of safety tongs 5 enters
The hydraulic oil that oil, rodless cavity oil return, the i.e. hydraulic oil of accumulator 2 and vibrations hydraulic mechanism 13 are extruded when shaking, all can pass through
Solenoid directional control valve 3 enters the rod chamber of oil cylinder 51, and the hydraulic oil in rodless cavity returns in fuel tank 7 by solenoid directional control valve 3, oil
The piston rod of cylinder 51 is retracted, the piston rod of oil cylinder 51 by connecting rod 52 pull safety block 53, safety block 53 clamp guide rail with
Braking car.
When after the failture evacuation of car, only solenoid directional control valve 3 need to be switched to right position, the oil cylinder 51 of safety tongs 5 without bar
The hydraulic oil that chamber oil-feed, rod chamber oil return, the i.e. hydraulic oil of accumulator 2 and vibrations hydraulic mechanism 13 are extruded when shaking is by electricity
Magnetic reversal valve 3 enters the rodless cavity of oil cylinder 51, and the hydraulic oil in rod chamber returns in fuel tank 7 by reversal valve 3, oil cylinder 51
Piston rod is overhanging, and loosens safety block 53 by connecting rod 52, and safety block 53 does not reclamp guide rail.
On the other hand, during if the user while take elevator, find what special status elevator has, and can pull manual reverse of direction
The commutation handle of valve 4, switches right position by hand-operated direction valve 4, and now, the rod chamber oil-feed of the oil cylinder 51 of safety tongs 5, rodless cavity returns
The hydraulic oil that oil, the i.e. hydraulic oil of accumulator 2 and vibrations hydraulic mechanism 13 are extruded when shaking, all can manually reversal valve 4
Enter the rod chamber of oil cylinder 51, and the hydraulic oil in rodless cavity is during manually reversal valve 4 returns to fuel tank 7, the piston of oil cylinder 51
Bar is retracted, and the piston rod of oil cylinder 51 pulls safety block 53, safety block 53 to clamp guide rail to brake car, energy by connecting rod 52
It is greatly improved the safety of elevator.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, it is also possible to making some deformation and improvement, these broadly fall into the protection model of the present invention
Enclose.
